alternative to calltree ?

[Bernd]

Hi *,

i'm searching for a program/script that will outline in text/graph the
call hierarchy of a perl script.

Unfortuantely, I can't get "calltree.pm" to work on a Win32 cygwin
system. There are error messages with B::* modules.

Does anyone know such a software? Any tips appreciated. Thanks in
advance!

Bernd
